A parliamentary system is a system of democratic governance of a state in which the executive branch derives its democratic legitimacy from, and is held accountable to, the legislature; the executive and legislative branches are thus interconnected. In a parliamentary system, the head of state is normally a different person from the head of government. This is in contrast to a presidential system in a democracy, where the head of state often is also the head of government, and most importantly, the executive branch does not derive its democratic legitimacy from the legislature.
Countries with parliamentary systems may be constitutional monarchies, where a monarch is the ceremonial head of state while the head of government is almost always a member of the legislature, or parliamentary republics, where a mostly ceremonial president is the head of state while the head of government is regularly from the legislature. In a few parliamentary republics, such as Botswana, South Africa and Suriname, as well as German states, the head of government is also head of state, but is elected by and is answerable to the legislature.

A parliamentary system is a system of government in which the ministers of the executive branch are drawn from the legislature and are accountable to that body, such that the executive and legislative branches are intertwined. In such a system, the head of government is both de facto chief executive and chief legislator.
Parliamentary systems are characterized by no clear-cut separation of powers between the executive and legislative branches, leading to a different set of checks and balances compared to those found in presidential systems. Parliamentary systems usually have a clear differentiation between the head of government and the head of state, with the head of government being the prime minister or premier, and the head of state often being a figurehead, often either a president (elected either popularly or by the parliament) or a hereditary monarch (often in a constitutional monarchy).
